Digital Demultiplexer (Demux) What is Digital Demultiplexer (Demux)? A digital device capable of forwarding its single input onto any one of the output lines is called Demultiplexer abbreviated for DEMUX. It is the reverse of Multiplexer. A Demultiplexer has a single input and multiple outputs. It has 2n output lines where “n” is the number of control signals. Each combination …

Digital Flip-Flops – Types & Operation of Flip-Flops What is Flip-Flop? Digital flip-flops are memory devices used for storing binary data in sequential logic circuits. Latches are level sensitive and Flip-flops are edge sensitive. It means that the latch’s output change with a change in input levels and the flip-flop’s output only change when there is an edge of controlling …

Energy Efficient Lighting & How to Implement It It has been estimated that lighting accounts for about 20% of the total power generation of the world. The quality and quantity of light not only affects our health, comfort, safety and productivity but also affects the economy. Many nations have been spending a huge amount of their electricity budget on lighting. …

Light Emitting Elements and Their Types INTRODUCTION The use and application of light cannot be overemphasized. Our natural source of light being an electromagnetic radiation that reaches us from the sun. Without that radiation, no life would remain on this planet. The ultraviolet ray reaching us from the sun is trapped by the green plants. They make use of it …

Arduino PWM Programming and its functions in Arduino What is PWM? PWM stands for “Pulse Width Modulation”. This technique is widely used in almost all devices in which voltage variation is required. In PWM, steady DC Voltage is converted into square wave with varying pulse width and the ratio of the total time period (T) of the wave to the …

PCB Designing: How To Design a PCB (Step by Step & Pictorial Views with Example PCB of LED Flasher Circuit) What is PCB “Printed Circuit Board” ? PCB stands for “Printed circuit board”. On this board all the components are soldered and interlinked by the copper tracks. The PCB can be a single layer and can go up to many …
